Iron complexes of corrole and porphyrin bearing electron-withdrawing meso-C6F5 groups had been used for the electrocatalytic evolution of hydrogen. In neutral buffer solution, evolution of hydrogen turnover frequency (TOF) values for iron corrole and iron porphyrin were 274 and 233?h?1 at an overpotential of 838?mV versus standard hydrogen electrode (SHE). The corresponding TOF values had dropped sharply to 19.79?h?1 and 14.36?h?1 in acetic acid media at an overpotential of 942?mV versus SHE. Interestingly, hydrogen evolution catalyzed by Fe(III) porphyrin was mainly via an Fe(I)-H intermediate, while a higher valent Fe(III)-H intermediate was observed for Fe(IV) corrole.
Halogeno-coordinated iron corroles

The first full assignment of 1H NMR chemical shifts for iron corroles and the first synthesis of a series of (halogeno)iron corroies reveal very large effects of the axial ligands on the corresponding spectra, which apparently reflect differences in the relative importance of metal-to-corrole and corrole-to-metal π-donation. These findings pave the way for a thorough analysis of the electronic structures of such complexes.
Hangman effect on hydrogen peroxide dismutation by Fe(iii) corroles

Hangman Fe(iii) corroles catalyse H2O2 disproportionation at a faster rate and display a more pronounced hangman effect than their one electron oxidized analogues owing to their ability to bypass high energy intermediates by redox-leveling derived from the use of the corrole as a non-innocent ligand.
